The Enterobacteria is a virus, this virus or bacteriophage infects certain bacteria.in the lambda phage it is   specifically E. coli. The wild type, having a temperate life cycle it allows the virus to exist in 2 life cycle stages, A lysogeny and a lytic stage. During these life cycles it destroys the cell through the process of lysis, during the lysis process the offspring of the virus are released from the burst cell.

Certain mutated strains of the virus enter a lytic stage, instead of lysing the cell. During this phase they saturate the cell with the copies of the bacteriophages of an already lysed cell.

The cell has a capsid (head) and a tail, the capsid carries a double stranded DNA which carries the infectious genetic coding material. During this phase, the virus locates coding that allows it to bind to the E. coli. The bacteriophage, then injects genetic material into the cell. This usually occurs in the lytic phase. After this the virus will hijack the bacterial DNA, it then uses the cells internal structures to produce many copies of the bacteriophages, this fallowed by lysis and the virus is set free to infect other cells.

During the lysogenic phase, the virus may insert its self into the DNA of the bacterial DNA. The virus may then develop into a non-parthenogenic virus, where it exists as a commensal relationship and does not harm the bacterial cell.
